挤塑板和保温板的区别
作者:admin 来源:本站 发布时间:2018-10-31 15:16:32 浏览次数:224

挤塑板和保温板两种彻底不同的保温资料,硅酸盐保温板是一种无机保温资料,防火功能好,为A级资料,不燃型。但该资料缺点较多,保温功能只要挤塑板的一半,资料密度较大,一般都在每立方200公斤以上,耐水性较差。挤塑板是一种有机保温资料,原资料为聚苯乙烯。保温功能很好,耐水性极好,但该资料防火功能一般,只能达到B1级难燃型。别的,挤塑板多用于屋面保温,用于墙体保温时,易呈现开裂、坠落等质量问题。还有一种保温资料为聚苯板,是现在使用最广泛的一种墙体保温资料,保温功能稍差于挤塑板,防火功能为B1级,经济实惠,使用技术成熟,不易呈现质量问题。

Extruded board and insulation board two completely different heat preservation materials, silicate insulation board is an inorganic heat preservation material, fire protection function is good, for class A inion, non-combustible. But the data has many shortcomings, insulation function as long as half of the extruded board, the data density is larger, generally more than 200 kg per cubic meter, poor water resistance. The extruded sheet is an organic thermal insulation material with raw materials as polystyrene. Heat preservation function is very good, water resistance is excellent, but the data fire prevention function is general, can only achieve B1 class flame retardant type. In addition, extruded board is mostly used for roof insulation, wall insulation, easy to appear cracking, falling and other quality problems. There is also a kind of insulation material for polystyrene board, is now the most widely used wall insulation material, insulation function is slightly worse than the extruded board, fire protection function is B1 level, economic and practical, the use of mature technology, not easy to present quality problems.

TDD保温装修一体板中的XPS挤塑板和PUR聚氨酯保温板十分像,但他们的也是有不同的,首要容重:XPS容重32公斤,PUR容重可达38公斤,导热系数:XPS导热系数在0.035,PUR在0.033左右,抗燃性方面,PUR也比XPS要好,但,PUR 也有欠好的当地,点燃的烟有毒,而且造价较高,表面做简单区分的就是PUR质地较细,摸起来会有粉末状颗粒坠落。
The XPS extruded board and PUR polyurethane insulation board in the TDD insulation and decoration integrated board are very similar, but they also have different, the first unit weight: XPS unit weight 32 kg, PUR unit weight 38 kg, thermal conductivity: XPS thermal conductivity of 0.035, PUR about 0.033, fire resistance, PUR is also better than XPS, but PUR also has a poor. Locally, the smoke ignited is toxic and costly, and the surface is simply distinguished by the finer PUR texture, which feels like powdered particles falling.
